I'll try to make this as short as possible.
I'm 25 now, I went to college and school with a girl called Sam... who I havent seen in 8 years. We have eachother on Facebook but we havent spoken in a long time. She was hot back then, but her Facebook pictures showed that she put a lot of weight on and cut her hair short - not my kind of thing, wasn't attracted.
About a month ago, Sam posted something about being accepted at University, I didn't think much of it... until I saw that she posted a picture of herself on Halloween, where she put makeup on half of her face, she looked HOT! So I popped up and messaged her. I'll put the conversation below:
Points to note: the reference about stabbing anybody in the bum, is because she fell over and stabbed a small knife into a guys ass cheek...
Me: That Halloween pics great. Are you doing something to do with makeup at Uni then?
Her: A ha nah!!! Thanks I'm doing criminology and criminal justice xxx
Me: Nice, you'll smash that you can go far in that kind of thing. I'm only just going back to college lol
Her: I'm really enjoying it x what u doing at college hope u all good too xxx
Me: Thats good you should stick at that, you'll be rich

haha. I'm doing accountancy, but doing my Maths and English GCSE's fast track at the same time
Wouldnt of thought we'd go back into studying when we dropped out of *college name here* lol
Her: That's good to do youll be minted in the long run xx I thought that when went back last year xx
Me: I'm really glad you're doing well for yourself. What are you hoping to do after the course?
Her: *3 big cheesy grin faces* I'm gonna do my masters degree in social work which basically gives me the opportunity to earn silly money xxx
Me: Fuck me you'll make a killing
Might have to marry you one day lol
Her: Ha ha ha xx
xxx
U go out much x
Me: A little bit, I used to go out more but I cant handle my drink lol I end up thinking I'm gorgeous when I'm drunk. More into pubs than clubs though. What about you?
Her: Not a lot as work weekends some times and if do go out of *town where we live* xxx
Me: Ye I wouldnt really go anywhere in *town where we live*, Spoons is ok but been too many times. We need a catch up one of the days though its been years
Her: Yeah defo we should go for a drink let me know when free xx
Me: As long as you promise not to stab anybody in the bum

Whats your number, or snapchat?
Her: What's urs I'll tx u and my sbapchat is *snapchat*
X
At this point I gave my number, she text me hers... and I added her on Snapchat
We've spoken a little on Snapchat in the past week, but it was instantly boring compared to Facebook. She posted a picture on her snapchat story basically timeline) of her with purple in her hair, so I said "Make sure you've got your hair like that when I next see you

thats not bad" and she put "thanks xx" ...she was out, and busy... but did she not seem a lot more interested than that on Facebook? Is it because she remembers the old me, who got no girls, and was far from alpha (I was popular in school, as was she, but I wasn't one of the alpha guys or anything)
I've got a lot better looking, grown up a lot, and improved my game a lot... but I didnt want to go full out PUA on her lol--I didn't think it'd look authentic, when she knows the old me too well.
Any tips on where I went wrong, if I did? I've got ideas in my head, but I don't want to write them out on here and influence people.
Thanks...
